Triglycerides of 2.8 mmol/L are more serious. High levels of triglycerides in the body between 2.26-5.63 mmol/L may cause atherosclerosis, thrombosis, vascular embolism and other diseases. This is the time to start working on lifestyle changes as a way to lower triglyceride levels. Blood triglycerides are mainly of exogenous and endogenous origin. Endogenous triglycerides are synthesized by the liver and fat and other tissues. In addition to energy supply and storage, these triglycerides protect the internal organs as a basic component of the body. Exogenous triglycerides are food intake, the fat in food is absorbed by the intestinal mucosa after the action of lipase and bile acids, and then triglycerides are synthesized by its cells, from which most of the triglycerides in the human body are obtained, and endogenous only accounts for a small portion. Therefore, if you want to reduce triglycerides in the body, you must control your diet and reduce the intake of fat. Lifestyle adjustments include: 1. control diet, do not eat foods high in fat, calories, cholesterol and sugar, such as animal offal, fried foods and barbecued foods; 2. control weight, physical exercise, mainly aerobic exercise, aerobic exercise up to half an hour or more will start to burn fat; 3. avoid alcohol, which is also a common cause of elevated triglycerides. Medication is needed if necessary.
